I AGITATING AND MIXING APPARATUS.

Specification of Letters Patent.

Patented Sept. 2a, 1913.

Application filed January 20, 1912. Serial No. 672,364.

To all whom it may concern:

Be it known that I, WAL'rnnE. Tnun'r, a citizen of the UnitedStatesflresidlng at Reno, in the county of Washoe and State of Nevada,have invented certain new anduseful Improvements in Agitating and MixingApparatu's,'of which the following is a specification. a

The hereinafter described invention relates to improvements in apparatusfor agitating, mixing and the aeration of the liquid slimes, clay,cement, slurry and sludge generally; and the principal object being toprovide a distributing arm so constructed, and arranged to operate insuch a manner to overcome the objections which are present in the typesof devices of this character now in use in which the distributing armsextend radially from the rotatable reservoir.

In the devices now in use, the distributing arms extend radially fromthe rotatable reservoir and each arm is provided with a Series of outletnozzles extending from the rear surface of the distributing arms, thus,when the apparatus is allowed to remain idle, say, for over night, itwill be discovered when it is again desired to rotate the distributingarms, that it is very difiicult to do so, as the outlet nozzles willhave forced the material against the distributing arm following, andwhen the agitation of the material has ceased, the heavier particleswill have settled around each distributing arm, as the arms in theirstationary position will have arrested the flow of material.

.My improveddevice comprises a hollow, convolute distributing arm,provided with a series of outlet nozzles, projecting from the forwardsurface of the arm and extending in a direction opposite to the travelof the distributing arm.

To comprehend the invention, reference should be had to the accompanyingsheet of drawings, wherein-- Figure 1 is a vertical sectional view of myimproved device, showing the bearing spindle supporting the rotatablereservoir, the convolutely extending arm carried thereby, the directionof the flow of the material into and from the receiver being illustratedby arrows.- Fig. 2 is a top plan view of the receiver, disclosing theshape of my improved distributing arm and the arrangement of thedistributing nozzles projecting from the forward surface thereof.

Referring more particularly to the drawings,'the numeral 1 designatesany suitable form of receiving tank, preferably circular ,in shape, thesize depending on the amount of material to be treated. Mounted torotate about the upper end of a spindle 2 extending vertically throughthe center of the bottom of the receiving tank 1 is a bearing 3,provided in its center with a cylindrical cut out portion 5 whichprovides a seat for an anti-friction button 6 carried in a' seat 7 onthe upper end of the spindle 2. The bearing 3 is provided midway of itslength with a stepped portion 8 from the outer edge of which extends adownwardly projecting cylindrical flange 9, the same providing anenlarged chamber 10, hereafter termed a reservoir, the lower edgethereof falling short of touching the bottom of the receiving tank 1.The spindle 2 is provided at its lower end with suitable screw threads11 adapted to receive a nut or adjusting member 12, which is supportedon the upper surface of a hollow supporting plate 13, attached to somepermanent structure.

From the above description it will be apparent that an adjustablespindle is provided for the bearing 3, and the hearing may be raised orlowered within the tank as desired.

Extending horizontally from and rotatable with the reservoir 10 andpositioned at the junction of the stepped portion 8 and the flange 9, isa hollow, tubular arm 14, convolute in shape, and provided on itsforward surface, in the direction of its rotation, with a series ofangular-1y positioned, rcarwardly extending, downwardly inclined, outletnoz zles 14' through which the material to be treated is forced in jetstreams, in a hereinafter described manner. j

The means for circulating the material through the receiving tank andthe convolute arm, constitutes a rotary pump 15 operated from anysuitable source of power and having its intake connected by a suitablepipe or channel 16, the upper end of which communicates with theinterior of the receiving tank as at 17, and the exhaustof said pump isconnected by a suitable pi e or channel 18 with the receiving tank 1,tie pipe 18 at its outer end surrounding the vertical spindle 2 andextending vertically up through the bottom of the receiving tank 1,inside the flange 9, and terminating short of the point wherethedistributing arm 14 connects with the hearing 3, as shown in Fig. 1 ofthe drawings. A suitable packing 19 is provided surrounding the spindle2 where it enters the pipe 18, in order to prevent an leakage of thematerial that is being treate In operation, the material to be treatedis fedinto the receiving tank, in any suitable manner, until itoverflows the pipe 16 .and submerges the tubular arm 14. Motion nowbeing imparted to the pumpi15, the material will be drawn in throughpipe 16 and forced through pipe 18 into the rotating reservoir ormeinberlO, through the hollow distributiing arm I4: andout through theoutlet nozzles 14. Owing to the-disposition ofthe nozzles for the jetstreams and the forcing of the liquid therefrom, an impelling action isimparted to the distributing arm 14;, carried by the bearing 3, which issupported on' ,and mix the said material or pulp, and by employing theconvolute distributing arm and arranging the distributing jets onjthefront face thereof, the entire area of the receiving tank will becoveredupon one revolution of the arm, and the material agitated will not bebanked front of the arm following as thenozzles project. from theforward surface of the arm.

Fromthev above description it will be apparent that a completecirculation and agitation of the material is always in progress upon theoperation of the pump. After the material has been treated, the same iswithdrawn from within the receiving tank in any suitable manner asthrough the outlet 19.

Having now fully described my invention what is claimed as new and isdesired to protect by.Letters Patent is- 1. In an apparatus forthedescribed purpose, the combinationwith a holding receptacle for thematerial to be treated, of a reservoir rotatably supported therein, acurved tubular arm extending horizontally therefrom, a series of jetnozzles extending angularlyfrom the forward surface of said arm andarranged at an incline to the liorizontal plane thereof, of acirculating pump for the liquid material, of connection between the pumpand tank for the with drawal of the material and connection between thepump and the rotatable reservoir, through which the material enteringthe pump is forced into the reservoir under pressure. 7

' 2. In an apparatus for the described purpose, the combination with aholding receptacle for the material to be treated, of a reservoirrotatably supported therein, a convolute tubular arm extendinghorizontally angularly from the forward face of said arm and arranged ata downward. inclina tionn to .the horizontal plane thereof, of acirculating pump for the liquid material, of connection between the pumpandtank for the Withdrawal of the material and connection between thepump and the rotatable reservoir,' through which the material is forcedinto the reservoir under pressure.

8.- In an apparatus for the described purpose, the combination with aholding receptacle for the material to be treated, of areservoir-rotatably supported therein, a'convolute tubular arm extendinghorizontally therefrom, a series of jet nozzles extending g'angularlyfrom the forward face of said arm and arranged at an angle to thehoriifonthe liquid material, of connection be- Et weexilthe pump andtank for the with- E drawal oftheimaterial, connection between the pumpand the rotatable reservoir, through which the material entering the=pu1np is forced into the reservoir under pressure, and an adjustablespindle extend- 'ing vertically through the bottom of said for raisingor lowering the same and the arm carried thereby in the receptacle.

4. In an agitating apparatus for semisolid liquids, the combination witha receiving receptacle for the solution to be treated, ;a rotatingmember provided with an interior chamber supported in said receptacle, aconvolute hollow arm projected horizontally from said rotatablemember,'a plu- .rality of jet nozzles extended from the forgward surfaceof said arm, and means for supplying liquid under pressure into said armthrough the rotatable member within the receiving receptacle. l

In testimony whereof I havejsigned my name to this specification in thepresence of 5 two subscribing witnesses. WALTERE. TRENT.
